High reliability design
N6900 series has a comprehensive MOS protection circuit. No matter how much MOS is damaged, it will not cause short-circuit between the positive and negative polarity or the positive polarity and the control circuit. The damage of some MOSs does not accelerate the damage of others, which can be used continuously.
By distributed design, it is easy to replace or add power modules and is convenient for maintenance and power expansion.
N6900 is designed with power limit circuit and has fast response, which can prevent the load from being damaged due to over power.
N6900 adopts shielding technology, which has wide adaptability to harsh test environment, and improves the anti-interference ability.

Short-circuit simulation
N6900 series supports two modes for short circuit: manual and lock.

Manual: N6900 will be short-circuited when Short button is pressed. It will stop short-circuiting when button is released. Manual mode is suitable for debugging or R&D, avoiding measurement accidents due to misoperation.
Lock: N6900 will keep short-circuiting when Short button is pressed. It will stop short-circuiting when the button is pressed again. Lock mode is suitable for long-time short-circuit test.

Auto test function
The auto test can be used to simulate waveform. This function can improve the test efficiency and can be achieved by SEQ function on the menu. Up to 100 sequence files editing is supported. Each file can support 50 steps.

OCP( over current protection) test
During OCP test, N6900 will load under CC mode and check whether the DUT voltage is lower than cut-off voltage. If lower, N6900 will record the present loading current as the test result and shut the input to stop the test. If the DUT voltage is higher than cut-off voltage, N6900 will increase the loading current until the DUT voltage is lower than cut-off voltage or it reaches the Max. loading current.

Remote sense to improve measurement accuracy
Remote sense is also know as four-wire sense. When N6900 is working, it will cause a voltage drop in the leads between the DUT and terminals of N6900, which will affect the voltage measurement accuracy of the load.
When working under CV, CR and CP modes, to ensure accurate measurement, it is recommended to use remote sense. During remote sensing, terminals S+ and S- are directly connected to the output of the DUT, eliminating the voltage drop in the leads.

Charge& discharge test
Users can set different conditions on the front panel to meet their test demands. For example, when battery voltage is lower than initial voltage, N6900 internal counter will start counting. The counter will stop working until the battery voltage drops to cut-off voltage.
